Cyber attacks on U.S. and South Korean government agencies, companies and institutions have been called the “most aggressive in recent memory.” Attackers use botnets or networks of zombie personal computers that are infected with a virus. Denial of service comes in to play when the controlled computers are instructed to contact target websites on a repeated basis, which overwhelms the target websites.
More sophisticated e commerce websites protect against these attacks by using software that detects and shuts down suspicious traffic.
Protect your computers! Viruses can attack and leave no apparent signs that your computer has been contaminated. Software is available to identify and flag dubious traffic flow. Many companies offer a free scan, so make sure you update your antivirus software and run regular scans. Additional security for businesses with the potential for attack should purchase Cyber Liability insurance to protect against this risk.
